Lecture 2Requirements Analysis of Real-Time
Systems

The semantic framework and its notational schema
together comprise the modeling language, such as
the UML.

• The development process is divided into
  large-scale
• activities or phases
• Analysis
• Design
• Translation
• Testing
• All phases work on a model of the system.
• ROPES(Rapid Object Oriented Process of Embedded
  Systems)
• is based on an iterative lifecycle that uses the
  standard UML.
• We apply ROPES(see ROPES.pdf ) to our project.

• Terms used in Standard Document
• CSCI Computer Software Configuration Item
• SSS Software Sub-Sections
• CIDS Configuration Item Development Specification
• PIDS Preliminary Item Development Specification
